I deleted my Facebook account a few months ago and am not sorry I did. For the last couple of months, I've been thinking about deleting my Twitter account, too. It has become a creepy, toxic place. I'm stunned that Twitter has no problem with people who want to inflict additional misery on the parents of murdered children. It's not about the first Amendment. Twitter is a company – it can choose whomever it wants to be on its platform.
